GearDiary has done a very good review of myPowerALL MP3400 which will power many devices and gadgets including Treo phones. "We carefully pack our gear to go in our bag with our USB connectors and electrical cords… As for me, when I am at the airport, not only do I want to be queued up in line, but near a electrical outlet. Sure I love my thin Samsung and Palm Treo phones, but four hours of battery life? I’ll watch a DVD, but every movie is two-part viewing with my Dell laptop’s 2-½ hour battery life. And I miss some great shots because my camera is on its last legs from taking multiple batches of 100 photos a day."
